The percent of a group (of visits or visitors) that took a specific action of interest. Conversion can
encompass the entire visit population, such as the percent of all visits that involved a completed
registration. Conversion can also refer to a very small and precise action, such as the percent of people
at step 3 of a scenario who continued to step 4; or it can apply to a subpopulation, such as the percent
of knowledgebase searches that result in issue resolution.
